Usage Examples

1. Real-Time Gas Price Monitoring

from scripts.gas_estimator import GasEstimator

estimator = GasEstimator()
prices = estimator.get_gas_prices(chain_id=1)

print(f"Fast: {prices['fast']} Gwei")
print(f"Standard: {prices['standard']} Gwei")
print(f"Economical: {prices['economical']} Gwei")
print(f"Base Fee: {prices['base_fee']} Gwei")

Output:

Fast: 0.05 Gwei
Standard: 0.04 Gwei
Economical: 0.04 Gwei
Base Fee: 0.03 Gwei

2. Estimate Transaction Cost

estimate = estimator.estimate_gas(
    to_address="0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D",
    data="0xa9059cbb...",
    value=0,
    chain_id=1
)

print(f"Gas Estimate: {estimate['gas_estimate']} units")
print(f"Cost: {estimate['cost_usd']} USD")

Output:

Gas Estimate: 52108 units
Cost: 0.01 USD

3. Batch Multiple Transactions

from scripts.transaction_batcher import TransactionBatcher

batcher = TransactionBatcher()
transactions = [
    {"to": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "data": "0x095ea7b3..."},
    {"to": , : },
    {: , : }
]

result = batcher.batch_transactions(transactions, chain_id=)
